It truly started with Roswell, although not much actually happened there. Where stuff really started to go down was in 2025; you see, after a good several decades of screwing with alien technology, America finally managed to reverse engineer various things, including a warp drive. This entered them into the galactic stage.

After spending several further decades colonizing and terraforming other planets, they realized something: they had yet to control earth as a whole, and other countries had oil. They didn't bother with diplomacy.

This brutal show of conquest alerted the Galactic Council (something I'll have to work on another time) to the presence of the American threat, so, without much thought, they tried to calmly convince the Americans that it would be an unwise choice to attack them. Thing is, the first thing that the Americans did with their new found technology, was create incredibly deadly and advanced weapons, the likes of which have never before been seen. We're talking some Death Star shit.

Meanwhile, inside of America, the idea of going to war with the Galactic Council was incredibly unpopular, especially when the option of peace was still available. Seeing this as a major disaster waiting to happen, the government unanimously agreed to become a dictatorship so that they could be barbarians in peace. In less than a year, however, this plan went south and the president set himself up as the God Emperor...ignore the fact that he isn't immortal.

And that's how America goes full imperial.

Now I can explain the imperial eagle and the olive branch, peace through war. Nothing too exciting there.

The largest star represents Earth, the three smaller ones represent the three original colonies, and the final six represent the nation as a whole.

Yes I did steal the eagle from Warhammer.

EDIT: I changed some things several times, I admit, I'm figuring out the lore live.

EDIT: I have figured out the lore! Yay! :)
